REVERSIBLE PAP'EJR CLIP Filed July 30, 1929 INVENTOR Kennegv 1 2 Durham ATTORNEY Patented Apr. 22, 1930 PATENT OFFICE KENNET 1 .1 -DUR1-1AM, or SEATTLE, WASHINGTON 1 REVERSIBLE P APER CLIP I Application filed July 30, 1929. Serial No. 382,094;

My invention relates to the art of wire clips and more particularly to that type of clip which is intended to secure a plurality of sheets together. Paper clips have been pro- Sgduced for a number of years in a wide variety of types, each of which are designed to accomplish a particular purpose. In my paper clip I have endeavored to produce a clip of the simplest possible form which will enable 10. ane to produce them at a minimum cost.

In some paper clips already produced, such as shown in Patent #1578525, sharply pointed projections are provided to enable the clip to more securely engage the papers it is to fasten together. I have found that in such a design it is very difiicult to put the clip on a set of papers or remove the same without mutilating the papers.

In my clip I provide similar sharp-pointed projections but further provide that when the clip is placed on the paper or is to be removed the projections do not touch the surby face of the paper. This is accomplished by having the clip so shaped and proportioned .that it may be reversed after being put in position, and when so reversed will cause the pointed projections to come in contact with the surface of the paper and thus hold it securely. This reversal of the clip is in itself .9.; not new as it is shown on a clip of quite different design in Patent Number 1,317,416.

7 Having thus described my invention in brief, the obj ects'I obtain with my device are namely:

First, the production of an article of manufacture which admits of very economical construct'ion.

Second, a clip which is characterized by having pointed outward projections, which Q 1nayjat the will of the user be brought in contact with the surfaces of the papers to be securedtogether. 7

Third, a clip which is so constructed that it will lie flat to the paper it fastens together. .1.1; fourth object is the production of a clip, Whose; inner ends are so tightly pressed against the papers it secures that other papersi'can not be inadvertently caught under the same clip.

.11. 1 The above general objects of my invention together with others inherent in the same are obtained by the device illustrated in the following drawings, the same being a preferred form of embodiment of my invention where- Figure 1 is an edge view of my clip as it is normally secured to papers. a l Figure 2 is a face View of the same. l Figure 3 is an edge view similar to F igure, 1 except a reversal'has been executed within the clip which now places the pointed-projections on the outside of the clip. I

Figure 4 shows my clip as applied to a plurality of papers showing the pointed pro jections away from the surfacesof the paper.

Figure. 5 shows myclip with a reversal half completed. 7 I e I 1 1 Figure 6 showsthe reversal completed with the pointed projections biting. into the surface of the outside sheets.

Figure 7 is a sectional View taken the line 77 of Figure 6.-

Referring to the drawings. throughout which like numerals indicate like parts,,numeral 10' designates the wire forming myclip 75. which is bent back on itself as is shown in Fig; ure 2. This provides a bend 11 which shouldbe greaterthanthe maximum-thickness of papers it is'de'signedto fasten together. The opposite ends-of the wire,12 and 14 respectively forming gripping leg portions-cross at a point 16 which from my experience is shown proportionately in" Figure Sharply pointed projections 12A and 14A respectively'are, formed on one sideof ends i 12 and 14 respectively. The exact position of these-projections will best be understood by a careful study of the drawings. particularly of Figures 1,2, and 3. The projectionsmust beso located that when the clip is intheposi;- tion shown in Figure 3, the inner surfaces of theend's, or more properly legs12fand 14l must present a smooth, surface :for: the en:

along trance of papers.

Figure 1 which shows the clip in ,re verse'd position shows the pointed 'proj'e ctions'on the inside with the outs'ide -'of the' clip smooth.

F igures 2; and '5", which are faceview's show I rather clearly the positi nefthe p1iojctions.'"- myv Method 0 7 operation .clip in this reversed position with the out-' side projections pressed into the papers andholding them very securely.- I Y l/Vhen it is. desired to remove the clip a reversal of this operation will present the smoothsurfaces ofends 1'2and 14 and the clip will slide es- With' very-little eflort. I

Having thus described my invention and c its methodof operation, what I claim is z 1. 'A wireclip forfsecuring sheet materials by being reversed in; position thereon com pris ng abend, two legs which cross, outwardex'tending'projections on one'side of each ."leg so p sitioned as to form atoothe d jaw,

2. A wire clipfor sheet material comprising a return'ben'd hav ng two leg portions which cross near their extremities and outwardly extending projections on one side of said legs solooated that'in one positionth'e V projectionspoint inwardly toward each other and when reversed poin't outwardlyand away 7 '3. A wire clip for sheet material comprisly toward each other and when reversed point outwardly and away from each other.
